Harvest in May
Nothing to harvest in May for Zone 3A.
Next window: June
— 40 varieties, including Alaska Early Pea, Astro Arugula, Beauty Pink Radishes.
Key Tasks for May in Zone 3A
- 1 Start 329 varieties indoors this month under grow lights or in a sunny south-facing window. Use a seed-starting mix and bottom heat (70–75°F) for best germination rates.
- 2 Harden off transplants before moving outdoors — set them outside in a sheltered spot for increasing hours over 7–10 days before planting in the ground.
- 3 Direct sow seeds at the recommended depth and spacing. Keep the seedbed consistently moist until germination is complete.
- 4 Check soil moisture before watering — stick a finger 2 inches into the soil. Water only when the soil is dry at that depth. Consistent moisture is more important than frequency.
